Worked on the NationalSecurityAgency/ghidra repository to implement ARM64 COFF relocation support, specifically addressing the IMAGE_REL_ARM64_ADDR64 relocation type within the AARCH64 relocation handler. This involved adding a missing implementation path to ensure correct processing of 64-bit absolute addresses, thereby reducing relocation errors and improving the reliability of binary analysis for ARM64 COFF binaries. The work required in-depth knowledge of binary analysis, reverse engineering, and Java, as well as familiarity with ARM64 and COFF architectures. All changes were managed through Git, demonstrating a methodical approach to low-level feature development and integration within a large-scale open-source project.
